Title: Device for detecting defect of sheet
Inventor: HAYASHI KOJI
IPC: G01N21/892
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To improve detection sensitivity and accuracy by using a light reception means including a photoconductor with a reflection means at a non-light- reception surface side and a photoconductor with a rough face part at least at one portion of a surface. SOLUTION: The detection device of the defect of the surface or inside of a sheet 1 such as a plastic film is composed by equipping a reflection means such as an aluminum deposition film 24 in a photoconductor 21 for receiving diffusion light (b) being generated by a defect 5 caused by laser beams or the like from a light source part. Then, for example, while the sheet 1 is being run by a take-up roll, scanning is made in a specific direction by light beams (a) from a laser light source. The diffusion light (b) from the defect 5 entering the photoconductor 21 is detected by a photomultiplier or the like while repeating reflection or the like, but the leakage of the scattered light (b) is reduced by the aluminum deposition film 24 at the non-light-reception surface side for improving light reception efficiency.  Even if at least one portion of the surface of the photoconductor 21 is set to a rough face part with a specific roughness, surface reflection can be suppressed, thus obtaining the same effect.
